Control functions in nonseparable simultaneous equations models [PDF]

open access: yesQuantitative Economics, 2014
The control function approach (Heckman and Robb (1985)) in a system of linear simultaneous equations provides a convenient procedure to estimate one of the functions in the system using reduced form residuals from the other functions as additional ...

Integrating multi-task learning with a differentiable physics constrained framework for hydrological forecasting [PDF]

open access: yesScientific Reports
Accurate prediction of terrestrial water cycle variables like soil moisture (SM) and evapotranspiration (ET) is crucial, yet existing Deep Learning (DL) models face limitations. Many adopt Single-Task Learning (STL), ignoring inter-variable dependencies,

Simultaneous-equations models [PDF]

open access: yes, 2000
The estimation of simultaneous equations models (SEMs) is of great importance in econometrics [34, 35, 62, 64, 96, 124, 130, 132, 149]. The most commonly used estimation procedures are the Three Stage Least-Squares (3SLS) procedure and the computationally expensive maximum likelihood procedure [33, 60, 97, 106, 107, 119, 120, 143, 153].

State and Unknown Input Simultaneous Estimation for a Class of Discrete-Time Linear Implicit Models : A Heat Exchanger Pilot Process Application [PDF]

open access: yesE3S Web of Conferences, 2021
In this paper, the design problem of simultaneous estimation of unmeasurable states and unknown inputs (UIs) is investigated for a class of discrete-time linear implicit models (DLIMs). The UIs affect both state and output of the system.
